KECES Ephono+ Phono Stage with External Linear Power Supply

KECES Audio has established a reputation for electronics that prioritize stable power management, clean circuit layouts and long-term reliability. Within the analogue domain, phono preamplifiers remain a critical interface between turntable and line-level amplification, particularly as cartridge technologies continue to diversify. Positioned in this evolving landscape, the Ephono+ addresses both traditional moving magnet and moving coil systems while also accommodating modern optical cartridge designs, reflecting current developments in high-quality vinyl playback.

Key Facts

• Adjustable gain and impedance settings tailored to different cartridge types
• Front-panel subsonic filter for improved real-world vinyl playback
• Compact enclosure suitable for modern analogue setups
• Retail price set at € 1.200,-

Design and System Concept

The Ephono+ follows a clearly defined separation concept, physically isolating the sensitive phono circuitry from the power supply. The phono stage itself is housed in a compact enclosure, while all power-related components are placed in a dedicated external linear power unit. This layout aims to minimize electromagnetic interference and mechanical vibration, both of which can compromise low-level analogue signals. Solid enclosures, precise connectors and a restrained, functional design underline its role as a long-term component within a high-quality vinyl system.

Technology and Features

From a technical perspective, the Ephono+ focuses on adaptability. Gain levels and loading parameters are tailored to suit different cartridge types, ensuring proper matching and consistent signal integrity. For moving coil cartridges, multiple impedance options allow fine adjustment to the electrical characteristics of the pickup. Moving magnet cartridges operate at a fixed, industry-standard load, providing compatibility with a broad range of designs.

A dedicated equalization stage for optical cartridge systems extends the functionality beyond conventional phono stages. This makes the Ephono+ suitable not only for established analogue setups but also for users exploring newer cartridge technologies. The inclusion of both Cinch and balanced XLR outputs supports integration into a wide variety of HiFi and studio-inspired systems.

External Linear Power Supply

The external linear power supply delivers stable ±24 V rails to the phono stage and is designed to avoid switching noise and voltage instability. By relocating transformers and regulation circuits outside the main unit, the phono stage remains electrically quiet, an advantage that becomes particularly relevant when using low-output moving coil cartridges. Protective circuitry guards against overload and overheating, contributing to operational stability and long-term reliability.

Practical Use and Application

In everyday use, the Ephono+ is aimed at vinyl listeners who value flexibility as their system evolves. Users can change cartridges without replacing the phono stage, whether moving between MM and MC designs or transitioning to optical systems. The subsonic filter helps reduce low-frequency disturbances caused by warped records or mechanical resonances, improving amplifier stability and loudspeaker control. Thanks to its low noise floor and broad compatibility, the Ephono+ fits well into mid-range and upper-mid-range analogue systems.
